Definitions

  • the use of the cyclic alcohol component allows further increase in heat shrinkage percentage as it increases the amorphousness of the resulting film. It also increases product appearance property after heat shrinkage (i.e. suppression whitening due to shrinkage, shrinkage shading, crinkling, deformation, and/or uneven shrinkage in the direction orthogonal to the maximum shrinkage direction).
  • the wrapping films cut off from the heat-shrinkable film rolls are often processed into the shape suitable for loading onto the containers [labels (tubular labels), tubes, bags, and the like] by adhesion using a solvent (tetrahydrofuran, 1,3-dioxolane, or the like).
  • the use of the cyclic alcohol component (1,4-cyclohexane dimethanol component or the like) leads to increase in the solvent bonding property as well.
  • Examples of the phosphorus compounds include phosphoric acids (phosphoric acid, phosphorous acid, hypophosphorous acid, and the like) and the esters thereof (alkylesters, arylesters, and the like); and alkylphosphonic acids, arylphosphonic acids and the esters thereof (alkylesters, arylesters, and the like).
  • alkali metal compounds examples include hydroxides, carbonates, aliphatic carboxylates (acetates, butyrates and the like, preferably acetates), aromatic carboxylates (benzoates), and salts of the compounds having phenolic hydroxyl groups (salts of phenol, and the like) of alkali metals.
  • the alkali metals include lithium, sodium, potassium, and the like (preferably sodium).
  • Preferred examples of the alkali metal compounds include lithium hydroxide, sodium hydroxide, potassium hydroxide, lithium carbonate, sodium carbonate, potassium carbonate, lithium acetate, sodium acetate, potassium acetate, and the like, particularly sodium acetate.
  • the adoption of the particular electrode above which replaces the stained electrode surface with a non-stained surface, enables to keep the surface of the electrode fresh and fewer in staining. Therefore, even when film production is continued for an extended period of time, the electrostatic contact is always controlled at a certain high level, and accordingly the samples collected at various cut-off points consistently have the predetermined thickness distribution described above.
  • a tungsten wire electrode was placed between a T die of extruder and a casting roll, surface temperature thereof being controlled at 30° C, and a voltage of 7 to 10 kV was applied between the electrode and the casting roll.
  • a resin was melt-extruded through the T die above at a temperature of 280°C, and the extruded film was brought into contact with the above electrode and cooled on the casting roll to produce a film having a thickness of 180 ⁇ m (casting speed: 30 m/min). Bubble-like defects generated on the surface of the film thus obtained were determined by visual examination, and the casting performance was classified according to the following criteria:
